Application filed. April 12, 1907. Serial No. 367,831.

the following is a specification.

Vented certain new and useful Improvements carding or disintegrating apparatus for tobacco the object of which is to disintegrate the same for the purpose of making cigarettes or for other purposes.

The object of the invention is to provide an apparatus of this character in which a number of carding or disintegrating cylinders are employed and in so disposing said cylinders with respect to each other as to not only obtain a practically uniform carding action but to also obtain a practically uniform delivery.

The invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

A vertical sectional view of an apparatus embodying the main features of my invention is shown in the accompanying drawing.

In the specific form shown the main housing is indicated at 1 and is provided with an open upper or intake portion 17 and a lower or outlet portion 18 although it will be understood that this form of structure and the features to be hereinafter described are not specifically essential to a full realization of the invention which I do not wish to be limited except for such limitations as the claims import.

On the intake end 17 a hopper 16 is disposed through which the tobacco passes to the carding mechanism hereinafter described. The delivery end of the housing 1 is preferably provided with a conveyer and as shown the same consists of a belt 5 trained about rollers 4 and 6 having suitable bearings in the housing 1 not shown. Advisedly a belt tightener 7 of any conventional type such as that shown may be provided to maintain the belt taut. A delivery spout 15 is disposed in receiving proximity to the discharge end of the conveyer and if desired a delivery or carding member in the form of a brush 14 may be provided in a manner to pick up the tobacco from the conveyer and thrust it into the spout 15. Any

suitable driving means may be provided such as a belt 19.

The cross sectional area of the housing 1 is shown as floored or partitioned by a carding or disintegrating mechanism which as shown consists of two sets of carding cylinders although it will be understood that I do not wish to be limited to the use of two sets. The carding mechanism or cylinders are associated with means for preventing the uncarded tobacco from descending between the sets of mechanisms or between one set and the adjacent wall of the housing and as shown said means consists of a strip 2 disposed between the sets of carding mechanisms and an extension 3 projecting from one wall of the housing toward one set of cylinders. As shown each set of cylinders comprises three cylinders and I will first describe the set disposed at the left of the drawing.

8 designates a primary or carding cylinder which is provided on its periphery with a plurality of carding pins 20. Said cylinder 8 is adapted to be driven in the direction indicated by the arrow and preferably said pins 20 are inclined from the radial in the direction in which the cylinder is rotated. It will be obvious from the drawing that said cylinder 8 is disposed in receiving proximity with respect to the hopper 16 and that the tobacco passing through said hopper will descend upon said cylinder. If the feed of tobacco is at all times normal and uniform the carding pins of cylinder 8 will uniformly take up the tobacco and carry it downwardly and each pin will be loaded but the feed of tobacco is not always normal or uniform and it is sometimes fed in in bulky bunches so that it is impossible for the carding pins to uniformly take it up.

In order to avoid the expense of special feeding mechanism and to obtain a uniform action of the carding pins 20 upon the tobaoeo I provide means in the form of a combined feeding and carding cylinder 9. Said cylinder 9 has a portion of its periphery inclosed by a part 21 of the housing but that portion of its periphery adjacent the cylinder 8 is presented to the incoming tobacco in such a manner as to receive and act upon the same. Preferably said cylinder 9 is reduced in size or diameter with respect to the cylinder 8 and is provided with carding feed pins 22 on its periphery and which pins are preferably radially disposed. Said cylinder 9 is rotated desirably at a relatively reduced speed with respect to the speed imparted to the cylinder 8 and in a direction reversed to the direction of rotation of said cylinder 8 as indicated by the arrow. The action of said cylinder 9 serves to force the incoming tobacco toward said cylinder 8 so that the pins thereof can engage and take up the same but by reason of the fact that the surface speed of the roller 9 is reduced with respect to the surface feed of the cylinder 8 the pins 22 serve to thrust and hold the tobacco in engaging proximity to the pins 20 so as to insure each of the same carrying a capacity load. Vhile the pins 22 serve to feed the tobacco to the pins 20 it will be noted that by reason of the fact that the pins 22 are radially disposed the same will not release the tobacco as the pins 20 engage the same and the tobacco will be torn or stripped oft from said pins 22 thereby causing the same to perform the function of carding as well as feeding the tobacco although it will be understood that the cylinder 9 has a useful function merely as a feeding cylinder. Vhile the greater portion of the tobacco on the pins 22 will be stripped off by the pins 20 it will be understood that fragments of the tobacco may be retained on the pins 22. To prevent this defective operation I desirably provide delivery means preferably in the form of a roller 10 which is provided with peripheral and radially disposed pins In the most improved embodiment of the invention this delivery roll 10 is associated with both the cylinders S and 9 for the purpose of removing the tobacco from the pins 20 and 22 but the primary object of the roller 10 is to effect removal of the tobacco from the pins 20. As shown said roll 10 is disposed and constructed in such a manner as to serve as a carding element and to this end the pins 23 are of suiiioient length to project between the pins 20 and 22 with a sufficient working clearance between the ends of said pins 23 and the bodies or surfaces of the cylinders 8 and 9 to permit of free and independent speeds and operations. Said roller 10 is preferably reduced in diameter with respect to the diameter of the cylinder 8 and as shown is approximately the diameter of cylinder 9 and is driven in the same direction as the cylinder 9 and at a slightly increased speed with respect to the speed of the cylinder 8 which would be a speed considerably greater than the cylinder 9 attains.

It will be noted that the disposition of the elements 8 9 and 10 is such that while the adjacent surfaces of cylinders 9 and 8 and 10 and 8 respectively are traveling in the same direction the adjacent surfaces of the cylinders 9 and 10 travel in reverse directions and this arrangement permits of a very effective action of the pins 23 in stripping fragments of tobacco from the pins 22 and thrusting them toward the cylinder 8. The speed imparted to the cylinder 10 is sufficiently increased with respect to the speed imparted to the cylinder 8 so as to obtain an increased surface speed of the cylinder 10 with respect to the surface speed of the cylin der 8. The radial pins 23 will thus engage the tobacco carried by the pins 20 and readily withdraw the same from said slanting or inclined pins 20 and deliver the tobacco upon the conveyer 5. The operation of the other set of cylinders indicated at 11, 12 and 13 is precisely the same as the operation just described and both sets of cylinders are of the same construction. Both sets of cylinders deliver to the conveyer 5, the delivery from the set at the right of the figure being superimposed upon the tobacco delivered by the set at the left of the figure. The advantage of this arrangement is that the conveyer 5 is always covered with tobacco and the latter is not delivered intermittently so as to leave intervening blank spaces on the conveyer as might be the case if only one set were used. It will thus be seen that with my improved device a continuous delivery to the conveyer 5 will be made even though the tobacco is fed in very unequal quantitiesthrough the hopper. As hereinbefore stated the strip 2 will prevent uncarded tobacco from descending between the two sets of cylinders and the extension 3 will prevent uncarded tobacco from descending between the cylinder 11 and the right-hand wall of the housing 1. The disposition of the parts is such that the surfaces of cylinders 8 and 12 both travel upwardly when adjacent the strip 2 and the surface of the cylinder 11 likewise travels upwardly when adjacent the extension 3 thereby facilitating the action of the strip 2 and the extension 3 in preventing uncarded tobacco from descending to the conveyer 5.

Means are shown for driving the cylinders at the required speeds but inasmuch as said means does not form a feature of the invention as regards its specific structure it is illustrated diagrammatically in the simplest manner so that it may be incorporated broadly as a part of the invention.

The cylinder 3 is driven from a pulley 24 by a belt 25 trained about a pulley 26 on the shaft of the cylinder 8. The cylinder 9 is provided with a pulley 27 and the cylinder 10 is provided with a pulley 28 over which belts 29 and 20 respectively are trained, said belts being driven by a step pulley 31. Substantially the same arrangement may be provided for the other set of cylinders and as shown cylinder 11 is provided with a pulley 32 over which a belt 33 is trained and driven from a pulley 34. A single step pulley 35 j is shown in driving relation with pulleys 36 and 37 of the cylinders 12 and 13 respectively about which belts 38 and 39 are trained.
